Problems solved by technology

Although these have a redox potential above that of the frequently used nitroxide radicals and hence enable higher cell voltages when the dialkoxybenzene-containing polymers are used as cathode material, batteries which have been produced with these polymers described in the literature exhibit only low discharge capacities.
In addition, synthesis complexity is a further criterion for the usability of organic materials as active electrode materials.

Abstract

The present invention relates to polymers and to the use thereof in the form of active electrode material or in an electrode slurry as electrical charge storage means, the electrical charge storage means especially being secondary batteries. These secondary batteries are especially notable for high cell voltages, and simple and scalable processing and production methods (for example by means of screen printing).

Description

[0001]The present invention relates to polymers and to the use thereof in the form of active electrode material or in an electrode slurry as electrical charge storage means, the electrical charge storage means especially being secondary batteries. These secondary batteries are especially notable for high cell voltages, high power densities and simple and scalable processing and production methods (for example by means of screen printing).BACKGROUND OF THE INVENTION[0002]Organic batteries are electrochemical cells which use an organic charge storage material as active electrode material for storing electrical charge. These secondary batteries are notable for their exceptional properties, such as fast chargeability, long lifetime, low weight, high flexibility and ease of processibility. Active electrode materials which have been described for charge storage in the prior art are various polymeric structures, for example polymeric compounds having organic nitroxide radicals as active un...
